How to allow NTLM/Windows Authentication in Firefox

Updated: May 08, 2019 21:12

Introduction

By default, NTLM integrated authentication is not enabled in Firefox. When you access HelloID via Firefox and attempt to authenticate to an Active Directory IdP, you will be always asked to enter your credentials.

Follow these instructions to allow NTML authentication in Firefox.

Configure Firefox

Open Firefox and open the config page by typing about:config

Search for network.automatic-ntlm-auth.trusted-uris and press Enter.

Double click the preference name network.automatic-ntlm-auth.trusted-uris and enter the URL of the server where the AD IdP connector has been installed. The URL can be found in the authentication prompt when you first log in to HelloID (see the Introduction to this article). Click OK once you have entered the URL.

Now the authentication popup will not appear and the user will be automatically logged on to HelloID.
